Hi there,  
At the moment I do not have time for debugging, but the error comes from ray/rllib/evaluation/metrics.py. It wrongly interprets your video and assumes you want to only report mean,std,… You could in the meantime update the file,…

By nesting your output you can circumvent this. sorry to propose this but could you try  
`episode.custom_metrics.update({'video': {'eval':video}})`
